Aaron Chalmers speaks ahead of his Newcastle homecoming on December 15

Donaldson reckons he was signed to give the MTV star an easy ride and ensure his 100 per cent win record.

But he reckons Chalmers’ camp have picked the wrong man.

Donaldson said: “Here’s the thing: I’ve had about four fights in the last five months – one was a stoppage and one was a knockout – but I was tired of knocking people out so in the last few fights I was working on my defence, not trying to knock the guy out.

“But they’ve seen that and were looking for someone who couldn’t punch so hard. And in those fights I wasn’t hitting hard. They’re judging me based on that. They don’t know I can hit so hard.

“I’m an aggressive fighter and I’m tough and I’m strong, so I’m going to go in there and let bombs off. I’m 100 per cent going to shock him.”
